Successful object classification is highly dependent upon initial segmentation of an object from its background. For complex, real-world imaging applications, this task is extremely challenging and critical to the success of the recognition system. Traditional object segmentation techniques often rely heavily upon noise removal during preprocessing and subsequently employ image-level segmentation strategies. Because effective noise-removal strategies are often difficult to develop for real-world imagery, alternate methods are required for object segmentation. An alternate approach is to determine target/nontarget status of image regions at the pixel level. In this manner, noise removal and object segmentation are performed in a single process. The approach takes advantage of the large amount of information contained in present-day, multispectral imagery. The key issues associated with this approach are a robust pixel information representation and an information fusion algorithm to process pixel-level information.
